This seems to be a known issue for Lenovo servers. It turns out they cram a whole lot of drivers in there, more than other vendors. The only known workaround is to remove VIBs from the host that are not needed. This is also described in https://kb.vmware.com/s/article/2144200.

To find out what VIBs are installed, log onto the affected host using SSH and run this command:

PowerShell

1

esxcli software vib list

Once you have identified a driver that you want to remove, put the host in maintenance mode and this command:

PowerShell

1

esxcli software vib remove-nqlogic-nx2-provider

In my case I wasn’t using the qlogic nx2 driver so I removed it. Now you should be able to update the host using VUM,
